Memory of Computer - ROM and RAM

We must not confuse the meaning of the term ‘Memory’ with storage. Technical Data used in the field explained in computer courses in Rawalpindi. It is memory that works to process information. The CPU –base memory chip receives electro-magnetic pulses and processes them to generate further electro-magnetic pulses. But for processing the information in the form of electro –magnetic pulses it must have stored within itself some prior information.

That is, for example, it must be given prior information about how to recognize the sources (device) and take the input information and also must be given prior information to know where to give the output information. These information, called the BIOS or the Basic Input Output System, are written within the CPU-base memory at the time of manufacturing and cannot be erased. Some more details of computer courses in Rawalpindi are as under.

There are also other instructions stored which are necessary to optimize the function of the processor by allocating its location spaces for different types of operations. For example cache memory is used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller and faster memory which stores copies of the data from the most frequently used main memory locations. Hence, this memory is called the ROM (Read Only Memory), as it cannot be erased.

Besides this, to perform logical operations or processing data, some m ore space is required as computer memory where it can load the input information and perform the processing, and retain the output information until delivered. This is called the RAM (Random Access Memory), which the computer uses, when the user feeds information for operation. Every time the computer is switched off, whatever information were there in RAM get erased. But ROM information about the physical configuration of the computer remains with the support of the  motherboard battery. So, if the charge o f the motherboard battery is worn out, every time you switch on the computer you would require the computer to load the BIOS from the ROM default values.
